[audio]Telegraphy E.P. - Telegraphy
Micro samples of field recording that I made while roaming around abandon factory’s and houses in the Detroit area, are the next level of electronic music after the synthesizer and processor. It gives the impression of lofi but still maintains the electronic feel.

[texts]The measurement of elecrical oscillations in the receiving antenna (Volume Bulletin of the Bureau of Standards, Vol. 7, 295-299 (1911) Scientific Paper 157 (S157))
The author has already referred to the standardisation of the perikon detector, for the same conditions of frequency and coupling, by comparison with a thermo-element. He now makes use of this arrangement, a galvanometer of 2000 ohms' resistance and sensitiveness 1.28*10/sup -9/ amp being used with the dector. In the following table are given the received current and received energy, measured in this way for various sending stations, the measurements being made at the U.S...

[texts]On the advantages of high spark-frequency in wireless radio-telegraphy (Volume Bulletin of the Bureau of Standards, Vol. 5, 153-157 (1908) Scientific Paper 96 (S96))
Tissot has already pointed out the advantages of high spark-frequency when thermal detectors are employed. The author demonstrates that a high spark-frequency is also advantageous from the point of view of the telephone receiver. Rayleigh's and Wien's results are quoted as showing the rapid increase of sensitiveness with the frequency, and a curve of volt-sensitiveness is given for a pair of 800-ohm Schmidt-Wilckes head telephones of the type used for radio-telegraphic work...

[audio]Interpretations iono-14
To interpret is all in the eyes of the beholder. Different world views and opinions varies widely from individuals. All of us has our own unique sense of reality that we somehow like to share with the rest. Weather it's good or bad, you and I compute the external environment to our own liking. Keeping this in mind, "Interpretations" an album of collected dubed sound-scapes by Ionosonde's resident artist Telegraphy, pushes the listener into outer space where a sterile environment is present to be...

[audio]Alter Rd. iono-13 - Telegraphy
Dark Detroit techno with very heavy dubed soundscapes gives this album a place in the underground music scene. Telegraphy once again, delivers yet another minimal dubed techno sound that is a far cry from his signature sound. Using only analog gear, Telegraphy delves deep into the underground sound environment to catch vibrant tonalities. Some of his home made studio gear makes an appearance to support a rich sounding album.

[audio]Kurz Above iono-12
The twelfth release of ionosonde recordings is all about dub techno on a micro scale. Analog synthesizers were used in this album which explored the sonic wonders of the super high frequency (SHF) electromagnetic band where radars listen intently. This frequency rang goes by the name "the Ka band" or Kurz-above. Using only analog gear to produce the best sound quality as possible, Telegraphy recreates sounds that might be heard by a person who's in control of one of these radars...

[texts]Some experiments with coupled high-frequency circuits (Volume Bulletin of the Bureau of Standards, Vol. 7, 301-314 (1911) Scientific Paper 158 (S158))
The relation between the energy of oscillation in two coupled circuits and the coefficient of coupling is investigated. The primary aircraft is excited by means of a vibrator worked by an electromagnet, and this circuit excites the two coupled circuits under observation. The arrangement is taken as representing a sender and a receiving circuit with a detector circuit coupled to it. It is the energy relations in the last two which are studied...

[texts]Comparative sensitiveness of some common detectors of electric oscillations (Volume Bulletin of the Bureau of Standards, Vol. 6, 527-542 (1910) Scientific Paper 140 (S140))
The experiments were made with a buzzer as transmitter, capable of giving wave-lengths from 350 m to over 2000 m. The chalcopyrite-zincite (perikon) detector was used as a standard for comparison, measurements showing that the deflections obtained with this detector are proportional to the squares of the oscillatory currents as measured by thermo-element. For the comparison of detectors of other types with the perikon, the shunted telephone method and the variable coupling method were used...

All tracks were written and produced by Richard Sudney(Telegraphy) 2012. "Someone in Detroit" is a forty-five minute live set that embraces dark Detroit pop with pausing's of experimental Detroit tech-no, noise, and dark ambient sound-scapes. Telegraphy pushes the boundaries out of the occult electronic music scene and into the revealed sound environment. The whole intention of this live set is to be a continuation of the monumental live performance "Somewhere In Detroit" [iono-5]
